Question

If you were running an experiment to determine the temperature at which beans sprout the fastest and you were measuring the plant growth, what would be the independent variable, dependent variable and the experimental control/constants/controlled variable?

Answer 1

Answer:

independent variable: Temperature

dependent variable: Plant growth

experimental control/constants: Same type of beans

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment in order to bring about a measurable response. According to this question, the experimenter changes the TEMPERATURE to determine the beans' growth. Hence, TEMPERATURE is the Independent variable.

The dependent variable is the variable that the experiment measures in an experiment. In this case, the measured variable, which is the PLANT GROWTH is the dependent variable.

Experimental control or constants or controlled variable is the variable that is kept unchanged by the experimenter throughout the experiment. In this case, the experimenter will use the SAME BEANS for all groups of the experiment. Therefore, the BEANS is the constant.

Answer 2

For an experiment to determine the temperature at which beans sprout the fastest, the independent variable would be temperature, the dependent variable would be height/number of leaves of plants, and all other variables would be constant variables.

The independent variable is the manipulated variable supplied during research. In order to determine the temperature at which beans sprout the fastest, different planted beans would be subjected to variable temperatures. Hence, the temperature is acting as the independent variable in this case.

The dependent variable is the variable measured in the course of research whose value is dependent on the manipulated variable supplied. In this case, the growth of the beans would vary depending on the temperature they are allowed to grow in. Thus, the growth indicators such as height, number of leaves, etc., would be the dependent variable.

Controlled/constant variables are those factors that are kept the same in all subject groups during the course of research. Apart from the independent and dependent variables, conditions should be kept the same for all subjects.  All these conditions are referred to as controlled/constant variables.
